# Create companies in batch

`POST /v1/companies/batch/create`

## Request

- Base URL: `https://api.folk.app`
- URL: `https://api.folk.app/v1/companies/batch/create`
- Auth: HTTP bearer

Create up to 100 companies in the workspace. A record naming an existing company updates that company, as `POST /v1/companies` does, and its result says so. Each record is processed on its own: one that fails does not prevent the others from being created.

## Headers

- `Idempotency-Key` string: A unique key, such as a UUID, that makes retrying this request safe: a retry with the same key and body returns the original response without running the operation again. Keys are kept for 24 hours after the request completes.

## Request body

- object
  - `records` object[], required
    - `name` string: The name of the company.
    - `description` string: A short description of the company.
    - `fundingRaised` union
      - number: The amount of funding raised by the company in USD, as a number.
      - string: The amount of funding raised by the company in USD, as a string.
    - `lastFundingDate` string, date, nullable: The date of the last funding round for the company, in YYYY-MM-DD format.
    - `industry` string, nullable: The industry the company operates in.
    - `foundationYear` union
      - string: The foundation year of the company, in YYYY format as string.
      - number: The foundation year of the company, in YYYY format as number.
    - `employeeRange` '1-10' | '11-50' | '51-200' | '201-500' | '501-1000' | '1001-5000' | '5001-10000' | '10000+', nullable: The employee range of the company.
    - `groups` object[]: The groups to add the company to. You must provide group ids.
      - `id` string, required
    - `addresses` string[]: A list of addresses associated with the company. The first address in the list will be the company's primary address.
    - `emails` string[]: A list of email addresses associated with the company. The first email address in the list will be the company's primary email address.
    - `phones` string[]: A list of phone numbers associated with the company. The first phone number in the list will be the company's primary phone number.
    - `urls` string[]: A list of URLs associated with the company. The first URL in the list will be the company's primary URL.
    - `customFieldValues` object: The custom field values associated with the company, grouped by group ids. The format is the following: ```json { "<groupId>": { "<customFieldName>": "<customFieldValue>" } } ``` The group ids passed must also be provided in the `groups` field, otherwise a validation error will be thrown. The format of the custom field value depends on the type of the custom field: - `textField`: string, eg: `"Foo"` - `numericField`: number or numeric string, eg: `42` or `"42"` - `dateField`: ISO 8601 string (YYYY-MM-DD), eg: `"2021-01-01"` - `singleSelect`: string (option label), eg: `"Active"`. Use the exact option labels of the custom field (case-sensitive): an unknown label creates a new option. - `multipleSelect`: array of strings (option labels), eg: `["B2B", "B2C"]`. Use the exact option labels of the custom field (case-sensitive): an unknown label creates a new option. - `contactField`: array of objects with `id` property, eg: `[{"id": "per_20228901-ce2b-418c-a267-671823107d8c"}]` - `userField`: array of objects with either `id` (workspace user id) or `email` (workspace user email) property, eg: `[{"id": "usr_a23373bb-5296-4c59-b2e8-8f121707d562"}, {"email": "jane@example.com"}]` - `objectField`: array of objects with `id` property, eg: `[{"id": "obj_2f62707c-52c0-421a-a11f-68e1ce9610f4"}]` Passing a `null` value or an empty array will unset the custom field value.
